Eplivanserin (SR-46,349; planned trade name Ciltyri) was an experimental drug for the treatment of insomnia which was being developed by Sanofi Aventis.^[1]

Sanofi Aventis announced in December 2009 that it was withdrawing its application for approval of eplivanserin from both the U.S. Food and Drug Administration and the European Medicines Agency.^[2]

Mechanism of action

Eplivanserin is an inverse agonist on the serotonin receptor subtype 5-HT_2A. In contrast to older sedating drugs acting on 5-HT_2A receptors (e.g., mirtazapine, clozapine, risperidone), eplivanserin has practically no affinity to dopamine, histamine and adrenergic receptors.^[3]

Study results

In a placebo controlled Phase II clinical trial with 351 subjects, eplivanserin reduced the sleep latency by 39 minutes (versus 26 minutes under placebo).^[3]
